Just 2 ?. Can i put the fuel cut off on the fuel rail? Because it would be hard to put it on the fuel solinoid. I would also like to put the n20 pressure guage under the hood by the fuel rail. Is closer to the bottle the better?
P.S. I do have an TNT power ring for sale if anybody is interested.

 

The FPSS should be inline with the rail and solenoid. I put my nitrous press gauge under the hood, well thats where the sender is, I have the gauge on my pillar inside the car. It dosent really matter if its closer to the bottle or farther from it just as long as its reading n20 pressure between the bottle and solenoids.

 

The FPSS comes with D4 manifold that you can screw onto the fuel rail and then you can install the fuel solinoid hose onto the D4 manifold and run a line to the fuel solinoid. Will that work just as good as installing the D4 manifold on the fuel solinoid? The reason I'm asking is because the directions on the FPSS said you have to install the D4 manifold on the fuel solinoid.

 

I dont know anything about TNT kits, what the hell is a D4?

 

Here is my setup. The arrows are pointing to the FPSS and the fuel line feeding to it then to the solenoid. I hope this helps answer your question.
